Testcases Gif

Fast Olympic Coding is an extension to assist with various tasks in competitive programming. It is a ported and enhanced version of the corresponding Sublime Text plugin that also leverages the power of VSCode.

⚡ Overview

📜 Concurrently run, edit, and delete multiple testcases
👨🏻‍💻 Stress tester to find counterexamples
👜 Insert pre-written code from another file with automatic folding
🛜 Reads contests and problems from Competitive Companion
🏃 BLAZINGLY FAST! Asynchronous design + optimizations = 99% spam proof!

💻 Keybinds

Compile (if file has compile command and file had changed) and run all testcases: Ctrl+Alt+B
Stop all testcases: Ctrl+Alt+K
Delete all testcases: Ctrl+Alt+D
Run stress test: Ctrl+Alt+G
Insert file template: Ctrl+Alt+I

📥 Install within VSCode or at Visual Studio Marketplace

</> Setting Up

Provide run settings for the languages you use in settings.json. Here are some examples for C++, Python, and Java:

{
  "fastolympiccoding.runSettings": {
    ".cpp": {
      "compileCommand": "g++ -std=gnu++20 -D_GLIBCXX_DEBUG ${path:${file}} -o ${path:${fileDirname}/${fileBasenameNoExtension}${exeExtname}}",
      "runCommand": "${path:${fileDirname}/${fileBasenameNoExtension}${exeExtname}}"
    },
    ".py": {
      "runCommand": "python ${path:${file}}"
    },
    ".java": {
      "compileCommand": "javac ${path:${file}}",
      "runCommand": "java -cp ${fileDirname} ${fileBasenameNoExtension}"
    }
  }
}

We can use the following variables in the syntax of ${...}

Most of VSCode's built-in variables
${exeExtname} returns .exe for Windows and an empty string for other platforms
${path:*value*} normalizes *value* into a valid path string for the current platform

Settings per language

compileCommand (optional): Command to run before runCommand when the file content changed
runCommand: Command to run the solution
currentWorkingDirectory (optional): sets the current working directory for runCommand

📜 Testcase Window

📄 Other features include...

Show/hide the testcase details
Shortened details of testcases for huge outputs
- View full text by clicking on their corresponding arrows
Color supported output for compile errors
... and so much more!


View wrong answers in a diff view!

General setting for both Testcase Window and Stress Tester

font: Font family used to render text (restart extension to apply)
runSettings: Object of run settings
maxDisplayCharacters: Maximum number of characters to display for each output
maxDisplayLines: Maximum number of lines to display for each output

👨🏻‍💻 Stress Tester

Required files (naming scheme can be configured in settings):

<name>.[ext]: the solution to bruteforce against
<name>__Good.[ext]: the solution that outputs the correct answer
<name>__Generator.[ext]: to generate inputs for the other 2 files
- The extension provides a 64-bit integer seed input for random number generators!


Stress Tester was able to find an counterexample due to an integer overflow bug!

Settings for Stress Tester

goodSolutionFile: Full path for good solution file (supports ${...})
generatorFile: Full path for generator file (supports ${...})
delayBetweenTestcases: Amount of delay between generated testcases in milliseconds (minimum: 5)
maxRuntime: Maximum time in milliseconds the Stress Tester is allowed to spend on one testcase (-1 for no limit)

👜 Inserting Prewritten Code

Add the root directory of the templates to the settings
Remove trailing newlines for fold to work (folding is optional via settings)


Adding a tree reroot DP template without switching files

Possible settings

fileTemplatesBaseDirectory: Full path to the base directory of all prewritten files (supports ${...})
foldFileTemplate (default: false): Whether to fold the newly inserted prewritten code

🛜 Competitive Companion

Open the extension to start the listening process!


Using Competitive Companion to parse a CodeForces problem


We can parse an entire CodeForces Div.3 Contest!

Settings for Competitive Companion integration

openSelectedFiles (default: true): Whether to open all the selected files
askForWhichFile (default: false): Ask for which file to write testcase onto, even when a file is currently opened and only a single problem has been received
includePattern (default: **/*): Glob pattern to filter in the included files for asking prompt
excludePattern (default: empty): Glob pattern to filter out the included files for asking prompt
